The industrial power supply system typically comprises a radial cable network operating at medium and low voltages. It is located within the building, close to where personnel work. It comprises MV transformers, switchgear, circuit breakers, relays, releases, fuses, motors, and power distribution panels. The two biggest challenges are ensuring personnel safety and supply reliability. This involves minimising incident energy while ensuring sufficient discrimination among protection relays for various network configurations and short-circuit contributions.
